At the end of last season, Pete suffered from a heart attack while no one was around except his son, Lucas, while Addison met a mystery man who asked her to go to Fiji. The team attempts to save Pete's life, but there could be complications due to how long it took to get him treatment. His wife, Violet, is still missing somewhere in LA. Addison reunited with Sam for her happily-ever-after, but can't quite get there due to her baby problems. The solution? Her mystery man, Jake Reilly (Benjamin Bratt), who -- no surprise here -- happens to be a fertility specialist. Drama indeed. (Unless Addison does the logical thing and hires someone else, but that's probably not going to happen.)

To top off the drama quota, Naomi has left Oceanside Wellness (which has been renamed Seaside Wellness Center) leaving a vacancy for a possible fertility doctor to fill, while Sheldon tries to help Amelia battle alcoholism, and Cooper and Charlotte face issues after someone from his past appears.

Private Practice Season 5 premieres tonight at 10 PM on ABC.
